I still cannot describe the "odor"… I still cannot describe the "odor" after Sleep8 finish its cycle: it is not as the smell after rain (that one I do like), but the smell I get during and after the cycle is not pleasant (is not noxious)... Not sure if its the blue bag, the charcoal or what... I have cleaned the whole water receptacle, tube and mask, I've tried only the tube, but in all, the odor remains the same... Is it possible I am not using it correctly? Is it normal?

Great little machine Works as described, super easy, plus I can store it away during while not in use - unlike the competition which requires a constant night table area.

Stinky hot mess We, too, overwhelmed with stink. Smells electrical and won't dissipate after cleaning. Thought maybe the rubber bag. Will try another week before returning. Very dissatisfied because of the stink. I've used 1 week awaken 3 times with headache after cleaning equipment daily. Nice try but stinks.

I like the ease of use of the system I like the ease of use of the system, and would rate the product higher if the smell was not so obnoxious. After each cleaning, I have to wash everything in order to get rid of the smell. This totally defeats the purpose of using the machine which I had hoped to use at home and when traveling. After I started using the product my allergies became worse due to the strong ozone smell. If this problem could be eliminated, I would keep it. Otherwise, I have invested money in a product and an extra bag that is not useful. I wonder if there is any evidence that the smell/ozone could be harmful to someone who has respiratory allergies? I would appreciate a reply and references to support the answer. Thank you.
